I have this exact same player. You do not need to install the bootloader. It should come already installed. All you need do is charge the player, which you apparently have done, and then hook it up to the computer. Note: (This might be your problem) the device must be turned off when you plug it up to the computer. If that doesn't work, let me know and I will try to help you further. You can write me off list at: professordean_at_gmail.com if you need further help.

Remember that when depression strikes, it is only temporary. If you choose not to believe so, just remember that if you let it end there, you'll never know what life had to bring later...

After charging the player, I installed the bootloader x5_fw_.bin in to the firmware folder as directed by the manual.
I then disconnected from the pc and plugged in the charger. After a short while I then reconnected to the pc.

For some reason now the hard drive won't spin up, it sounds like it tries to do so twice and remains in action for about five seconds spinning up, dying, trying to spin up again and finally stopping. There is a message that comes up saying audio and then it reverts to charging.
I'm assuming here that I'm still turning the machine on by sliding the button on the top right of the player forward and holding it there for a couple of seconds or so?
